The complexity of causes

Mental retardation can follow any of the biological, environmental, and psychological events that are capable of producing a decline of cognitive functions. Some factors do not directly or inevitably cause mental retardation but add to the effects of a previous primary cause. Genetic causes may be hereditary or non-hereditary, and may or may not produce specific syndromes. Some lead to inborn errors of metabolism.(l)

Neurological symptoms during the neonatal period are strongly associated with prenatal developmental disturbances. For example in maternal pre-eclampsia, placental insufficiency may lead to malnutrition, fetal asphyxia, intrauterine growth retardation and prematurity, and subsequently to perinatal problems including asphyxia, intracranial haemorrhage, hyperbilirubinaemia, and hypoglycaemia. It is important to detect these coexisting conditions, because their effects may add to or interact with those of the primary cause.(23)

The biomedical cause of mental retardation may lead to additional disorders or disabilities, or may itself be progressive. (4,5) These additional factors affect opportunities for gaining experiences necessary for development. Activity may be restricted by sickness, or the effects of medication. Motor disability may reduce mobility, or cause dysphasia. Sensory impairment may restrict vision or hearing. These restrictions add to the effects of the primary cause and interact with environmental and emotional factors to retard the development of the individual. (6,,7)
